Heroines Guild
The Heroines Guild was a multiversal organisation made of female superheroes.
They had their headquarters on Earth-O147. At least one incarnation of Jenny Everywhere was a member of the Guild, regularly checking its website on her transdimensional phones for news and gossip about the members of the Guild.
At one stage in its history, the Guild was led by the sorceress Gina. However, following unknown incidents she was stripped of her powers both supernatural and hierarchical, being defeated by fellow Guild member the Silver Squirrel. Though not kicked out altogether, Gina was made the lowest-ranking member of the Guild and tied up in the Guild's lobby for some time to humiliate her so as to rub in her demotion.

Behind the scenes
Although Jenny Everywhere Visits the Heroines Guild was written by DeviantArt user Mattkind, they credited another user with the creation and ownership of the Guild as a concept, using it only on their authorisation.
